Y This invention relates to garden` lframes and other horticultural frames and houses having inclined glazing in the'top or light comprising overlapping pieces of glass, the 5 chief object being to provide for the admission of air to the interior of the frame or housing. I y v According to the invention the overlapping pieces of glass in the top or light of the frame 0 or housing have their overlapping portions distanced apart to afford between them passages for the admission ofair to the interior of the frame. Normally the top orlight will be mounted on the wall structure of the frame run down from one piece of glass to the other andV finally fallfoutside the-frame, whilst if it is desired to admit rain water to the interior the top or light may be reversed so that rain water falling on the pieces of glass Will run between the overlapping portions and drip off the lower edges of the pieces of glass on to the soil enclosed by the frame. In this .would preferably be arranged below the centres of the pieces of glass or between the overlapping portions thereof so that the drip-V in louvre formation so as to afford the air passages between f them, and fthe strips Vof glass are secured in position within the top or light lof the frame by hook members or clips which not only support the said strips but also serve-to distance their overlapping portions apart, said hooked members or'clips being secured to the side members of the top or light and engaging the edges of the glass strips. The top or light mayberemovably mounted upon the wall structure ofthe frame by means of appropriate slotted orrecessed brackets on the upper and lower transverse members of said top or light being engaged by tongues or projections on the rear and front walls of the frame. In this latter conso that rain water falling on the glazing will latter connection the plants within the frame r arranged overlapping strips distanced apart Y 3,4, the top or light can ybe turned back about nection thetongues or projections for engaging the slotted brackets may be pivotally con-- nected to the rear. andV front walls so as to; permitl the top or light to be raised either at v therear or front about saidhinged connec.-v p tions with the Wall structure. I

In order that the invention may be clearly understood and readily carried into effect, thel same will now be more fully described with reference to and by the aid of the ac-k companying drawings; in whichz- Y Figure lis an isometric View showing a horticultural frame constructed according to Y the invention. l Y n FigureQ is a sectional elevation taken o line A-A of Figure l. a n Figure 3 is a similar viewto Figure 2but: shows the top or. light of the frame reversed so as to allow lrain Waterfalling onthe glazing to run between the overlapping portions. Figure 4 is a detail view showing the hinge socket and hinge.v f i Figures 5 `and 6 are illustrative of ldetails hereinafter referred to. t

Referring to the drawings l, l are the walls of a horticultural frame, 2 isthe framework of the top or light, 3, 4 are hingedtongues and 5, 6 sockets whereby the said topv or light is positioned on the Walls 1,;andy 7, 7 are the overlapping strips of glass with which the so top4 or lightis glazed, These strips of glass are transversely arranged and distanced apart in louvre formation and secured in pofl sition Within the'framework 2 of the top light by meansof U-shaped clips 8, said clips 8 being secured to the side members of theV frame work 2 by vmeans of tacks (not shown),or in any other convenient manner. The side walls ofv the frame'project abovel the front Y and rear Walls to position the top orlight laterally and the side members oflthevlatter are provided with ledges 9 for supportingy the ends of the glassstrips 7, whilst the front and rearedges of saidftopV or light are Ypositioned by means of the hinged tongues 3, 4 on the wallsy l, l ofthe frame taking into Y sockets 5, y6- onrthe said front and `rear edges respectively Vof the top or light. It will be seen that, by the use of such, hinged tongues either its front or' rear edge as indicated by the arrows in Figures 2 and 3, or if desired can be lifted bodily oft the frame 1. In this l connection the top or Vlight may have crosspieces adapted to aord handles for lifting and the engaging edges of thehinged tongues 3, 4 may be bevelled and tapered (see Figure 4), so as to pass more easily into the sockets 5, 6. ln addition to the clips 8 the glass strips 7 are preferably further supported at their ends by putty or thev like 11';

oi rubber or like resilient wedges 12, seeFigure 5, may be substituted for the clips 8 and putty 11. Also, ifdesired, rubberv strips 13, see Figure 6, of wedge shape in section may be provided for sealing the gaps between the glass strips 7 in very cold weather, and in this connection said strips will be especially applicable in the case of greenhouse glazing.

It will be seen that the present inventiony provides for the admission" of air to the interior of a garden frame by way of passages afforded between the overlapping portions of the pieces or strips of glass in such a manner as will ensure the circulation of the air to prevent condensation on the inner surfaces of the glass. Moreover,l by reversing the frame, rain water may be admitted to the interior in addition to air by way of the passages-between the overlapping portions of the pieces of glass, whilst if it is desired to admit still more air the top or light can be raised about one or other of its hinged connections with the wall structure and propped bars for supporting a plurality of panes of glass ina predetermined fixed relationto said frame and in overlapped relation. toeach other, said panes having their Voverlapping edges spaced apart by said supporting means to afford Ventilating openings.

l 2. A greenhouse construction comprising a rectangular frame including pairs of paral lel side and ends bars, said side bars having substantially vertical faces, and means on .said

. faces for supporting a plurality of panes of glass in a predetermined fixed relation to said frame and in overlapped relation to each other, said panes lhaving their overlapping edges spaced apart by said'supporting means to afford Ventilating openings.

3. A construction in accordance with claim 1 characterized bythe fact that said rectangular frame is adapted to be bodily removed and replacedin a reversed position so that water falling onthe panes of glass will run between the overlapping portions and drip off the lower edges of the panes of glass on the soil enclosed by the frame.

4. A greenhouse construction comprising substantially vertical front and rear walls and arectangular top light frame including pairs of parallel side bars anda pair of parallel front and rear end bars, said end bars each having a removable hinge connection with said front and rear wall respectively, whereby said top light frame maybe swung forwardly or rearwardly'on one or the other of said walls, said side bars having means for supporting a plurality of panes of glass in a predetermined lfixed relation to said frame and in overlapped relation to each other, said panes havingY their overlapping edges spaced apart by said-supporting means to afford ventilating openings.

5. A greenhouse construction comprising substantially vertical Vfront and rear Walls and a rectangular top light frameremovably mounted on the wall structure by meansof slotted brackets on saidframe engaged by tongues projecting upwardly from said front 4 and rear walls, respectively.

6. A construction in accordance with claim 4, characterized bythe fact that said removable hinges comprise tongues hinged to said vfront and rear walls and sockets fixed to said front and rearV bars of saidframe respectively, said sockets being adapted to receive said tongues to removably secure said frame in position on said wall. f 7. A construction in accordance with claim 4 characterized by the fact that said removable hinges comprise tongues hinged to said front and rear walls and sockets fixed to said front and rear bars of said frame respectively, said tongues having their upper edges tapered to facilitate entrance into said sockets, said sockets being adapted to receive said tongues to removably-secure said frame in position on said walls. Y
